If an hour is equal to 1, then we know that the answer is more than 3. 12 minutes is equal to 1/5 of an hour, and if we add 3 and 1/5, we get the answer.

3 1/5

Answer:

Jake's running time as a decimal is:

3.2 hours

Step-by-step explanation:

We are given that:

Jake completed a marathon race 3 hours and 12 minutes.

We know that:

1 hour= 60 minutes

1 minute= 1/60 hour

12 minutes = 12/60 minutes

                  = 0.2 hour

3 hours and 12 minutes= (3+0.2) hours

                                      = 3.2 hours

Hence, Jake's running time as a decimal is:

3.2 hours

Suppose that x and y vary inversely, and x = 12 when y = 8 . Write the function that models the inverse variation.
Alja [10]

Answer:

y=\frac{96}{x}

Step-by-step explanation:

So when x and y, vary inversely, it means that the product of x and y will remain constant such that: xy=c. This means that the function can be defined as y=\frac{c}{x} by dividing both sides by x. In this case x=12, and y=8, this means the constant is equal to 12 * 8 which is 96. So we have the equation:  xy = 96, which can be defined as y=\frac{96}{x}

WILL GIVE BRAINLIEST THANKS AND 5 STARS FOR CORRECT ANSWER Desmond ran a lemonade stand in front of his house for the fans walki
Fiesta28 [93]

Answer:

56

Step-by-step explanation:

First, convert the 70% so that we can use it with the 80 cups. To do this, convert the percent to a decimal by moving the decimal 2 spaces to the left:

70% → 70.00 → 0.70 → 0.7

70% percent can be seen as 0.7. Multiply this by 80:

80*0.7=56

So, 70% of 80 is 56. Desmond sold 56 cups on the second Saturday.

:Done

Len [333]

Answer:

Step-by-step explanation:

3/x = sin45

x = 3/sin45

x = 3 / ½(√2)

x = 3(2/√2)

x = 3((2√2)/2)

x = 3√2
